The complete set Dynamic L 2 guarantees with action models and the three 180° curves having more fun. With a length of up to 4.50 m offer the three different action course limitless ball track pleasure. The four high-speed curves with increased margin allows maximum velocity of the ball in the curve! Fast-paced race the balls on the mechanical points in different railway circuits. You shoot through the exchange point in the direction of the gyro funnel or via a rocker the ball on the stop point. The 180°-curve allows young architects a change of direction of the ball in a confined space. Further harassment, the ball again via looping and for recording location of the lift. At the bottom of the recording location arrived, the balls over the with a XS-Motor-driven lift again right to the top. The four didactic attempt models explain the way the effects of different physical phenomena (acceleration, inertia, balance of power, of the conservation of energy, pulse rate, Motion Laws). On the
